clam
a clam, protected between two hard shells
a kind of sea animal – mollusc – a general name given to any of small to large shellfish with two equal shells with a hinge that close the animal in (bivalves); soft body without head or eyes, but with kidney, heart, mouth, arm-like organs to dig the burrows or to move, etc.; feed on plankton (= very tiny plant-like creatures in water) which they get by filter feeding (= taking the water in and passing it through fine feather like organs that filter the tiny particles); as the name is a general term used loosely for any bivalves, it is not easy to give a number to all the species (kinds); on average, live for 10-20 years, it is estimated that some species live up to 40 years; found on sand or in mud (silt) in sea waters all over the world

The shells of clams have been worn as ornaments, used as money, and used for decorating places for thousands of years by people. They have been a very good food source for many people for many years. There are large clam farms in many places around the world. The reproductive system in clams is very interesting: in some species the male releases sperm into the water and the females release millions of eggs, and the eggs fertilise in water; but in some species the same parent clam releases sperm first and then the eggs into the water, and the eggs fertilise in water.
